In a large pot, heat the olive oil over medium-high heat. Add the sliced beef, season with salt and pepper, and brown on all sides (about 5-7 minutes). Remove the beef from the pot and set aside.
In the same pot, add the diced onion and mushrooms. Sauté for about 4-5 minutes until the onions are translucent and the mushrooms are tender.
Stir in the minced garlic and paprika, cooking for an additional 1-2 minutes until fragrant.
Sprinkle the flour over the mushroom mixture and stir well to combine, cooking for another minute to remove the raw flour taste.
Slowly pour in the beef broth while stirring to avoid lumps. Bring the mixture to a gentle boil.
Add the wide egg noodles to the pot, stirring to ensure they are submerged in the broth. Reduce heat to a simmer, cover, and cook for about 10-12 minutes, or until the noodles are tender.
Once the noodles are cooked through, stir in the browned beef and sour cream until everything is well combined and heated through. Adjust seasoning with salt and pepper if needed.
Remove from heat and let it sit for a few minutes before serving.
Notes
Serve in bowls, garnished with freshly chopped parsley and a sprinkle of paprika.
